Does anyone know if this fuel pump is correct for my 11D 1968 build 350/300 with A/T ?also is the "48K" part of the stamp on it the date code ? would it be Sept. 1968 ? (Delco skipped the "I" correct ? )

My big question is does anyone know if the 40725 pump will fit and work on my 350/300 auto '69 car ?It looks better than the aftermarket replacement one I have on now, with the correct AC logo and finish.Thanks for any help.Billy
